I've used it on my iBook (G4 800, 256kB L2 cache, 640MB RAM, 60GB hard disk), and it's usable, but not with many channels or effects. It's pretty slow, and not particularly enjoyable to use though. I use Protools too, and find that I can get a lot more done, and it's much more responsive. To me this says that Garageband is quite resource-intensive. Having said this, your iBook is quite a bit more gutsy than mine, so it should fare much better. The extra RAM and L2 cache should go a long way. In any case, I'd be interested to know how your friend's son goes (if he's not happy with it, I can take it off your hands! ;-) Depending on what he wants to do, a good program is Audacity. It's a basic multichannel recording program, and on any machine will allow similtaneous recording/playback of more channels than Garagaband will. So, if that's his focus, and he's running out of grunt to record lots of channels, there are other options. Another good program is Ardour. (both these are Free-software or the GNU variety) It depends what he wants to do. If he wants to only record live instruments, and layer sounds, mix down, etc, there are better options. If he wants to 'play' with loops, effects, software synths, etc, then Garageband is a good option and he might like more computing grunt.
